style(qbz-slint): album + playlist cards to 200px, fonts -2/-1

AlbumCard and PlaylistCard are now 200x246 (was 220x266), with the larger
texts -2px and the smaller ones -1px. All album/playlist carousels and grids
follow (card-width/height 200/246) so nothing reflows: Carousel,
PlaylistCarousel, AlbumCollectionView/AlbumGrid, ReleaseGrid, Spotlight,
HomeSkeleton, DiscoverBrowseView, SearchResultsView, FavoritesView. Artist /
radio cards are untouched.
